‘Do matrix signs cause traffic jams on the highway?’

‘I almost always see traffic jams on the motorway at the merging lanes because the matrix signs indicate 70 and 50 as the maximum speed’, says reader K. Peters-Bühler in the question & answer section of our car editors. ‘There is often nothing wrong and you can just drive on, but it is the signs that cause the traffic jam. I see this happening at Lexmond and Almere-Buiten, among others. If cars could continue driving normally when merging, there would be no traffic jams in those places.’
